This is a level 42+ side-quest. Depending on your build this can be a fairly easy quest or very hard. 1. Gather in Night Tear and you will discover a place called "Burnt-Down Tree"2. Beat the fight and get Wilrynn's Corpse Dust. (best method is mass debuffs + armor)3. Move to Gaea's Dawn and gather. You will discover Yaxxion's Remains.4. Beat the fight to obtain a Massive Dragon Skull. (best method is to use attacks that reduce life or lots of boosts + a damage to all attack)5. Move to Wildhowl and gather. You will discover a new place.6. Beat the fight to get an Unsealed Letter. (Best method is to just use as much armor+ward)7. Move to Draka and gather to discover "Salamaths Hidden Lab".8. Beat the fight to get a charm. "Dusty Gyrometer". (Best method is to use boosts + a damage to all)The charm you get requires Physics rank 1. You can get that from the academy in Lumina. After you max it move to Triland and fight Lez...Use just one of those Dusty charms and it will auto-kill Lez. Making it so you just have to kill the guardian. He is fairly easy to kill with DPS. Your reward is a summon that will raise both armor and ward to 70 if you have some armor/ward going.

I have no idea. I haven't done this quest yet. I just saw the dusty gyrometer on the recently found charms list and was curious about it. I found this walk through when I followed up on it. Once I go through it I'll let you guys know.

Yeah, you can run 5 of them-- all you have to do is beat the Mirage Tower in Triland five times.

A few other notes: BDT is a bitch of a fight for some classes, Nightmares, Voodoo Heads, and banes are the key to it. If you are lucky enough to have Salamanth's, you can use them as well. I tend to run that, plus a bit of armor and protect, to help keep the Vultures alive and kicking.

I've mainly done +next and AOE for Yaxions Remains. I THINK they're like the lil' guys in ACOTE, in that they'll bring each other back to life if one's dead.

I can't remember how I did Emerald Coast. That was the second hardest for most of my guys (BDT being, bar none, a pain). I think I have my Assassins' deck still saved, but might not.

Best method for Salamanths Hidden Lab is Mana Needle. You get it as a boss-drop from Water of Life, it still's non-ongoing magic buffs. So, Mana Needle the Firetraps, then throw one Banishing Flame Stone in. Watch as it goes boom.

For Mirage Tower, 5 Dusty Gyrometers, and an indirect damage strat. I (just because I like'em) used banes to do it. CPB is rather more problematic, since the Gyrometer's self-normalize.

The only charm that I know of that you can only get one of is Demoncrusher (man, I really need to do more Prelex so I can get mine . . . ).

I got it to work with lots of banes, lots of will destruction, and some armor. I think I went overboard on armor & will destruction, and under on banes, since I ended with 2 spirit and 800 health, but so it goes. Because he normalizes, the ongoing debuffs like feet bind & despair are useless. EDIT: Tabby already pointed this out.

Golem's Heart and Aura of Darkness would've been great, and echo shield may have helped, but it went fine like this. I probably should have added Eternal Ice instead of Dragon Aegis, but I didn't think of it at the time.

I haven't tried with anyone else yet, but I'm expecting my paladin won't be able to hack it, seal of the pure notwithstanding.

Willpower destruction, like Nightmares and Voodoo HeadsWoeful's whip can also be useful for mix of damage and spiritRestore charms like Restore faith, or better yet Salamath's JudgementStrong banes and summons

Paladins, use Divine Intervention, Aura of Preservation, and Sacrifice of the Pure. Anything to keep the Buzzards alive!
